Be it known that I, Jorm'll. GiBsoN, a citizen of the United States,residing at Bruin, in the county of Butler and State of Pennsylvania,have invented a new and use ful VVindow-Sash Holder, of which thefollowing is a specification.

The present invention relates to window sash holders the object being toprovide a window sash holder whirh is used in connection with a slidingsash and which will retain the same in any adjusted position.

A second object of the invention is to provide a window sash holderwhich will offectively retain the sash in raised position and which willat the same time prevent rattling of the sash.

A further general object of the invention is to provide a sash holderwhich is applicable to any vertically movable sash and which willdispense with weights, pulleys and cords that are now commonly used.

It is another important object to provide a window sash holder whichincludes a spring urged housing in which is journaled a roller forengagement with the window frame to retain the window sash in adjustedposition, and means associated with the roller and housing to preventthe roller from rotating in a counter-clockwise direction upon thelowering of the sash.

Still. another object of the invention resides in the provision of aspring actuated roller which frictionally engages the side rail. of thewindow frame to retain the sash in adjusted position, a novel mountingbeing provided for the roller which not only serves as a mounting forthe roller but as an abutment for the spring used in the con- Structionof the device.

An additional general object of the invention resides in the provisionof a sash holder having the above characteristics, which is simple inconstruction, which con sists of few parts and which may be manufacturedand placed on the market at a minimum cost.

With the above and other objects and advantages in mind, the inventionconsists of the combinations of elements, constructions and formations,arrangement of parts, and general assemblage, the details of which willbe hereinafter enlarged upon and recited in the appended claim, oneembodiment of the invention being illustrated in the accompapyingdrawings, wherein gure 1 is a sectional view of a window sash having myimproved sash holder mounted therein, parts being broken away;

Fig. 2 is a fragmentarysectional view of one of the side bars of awindow frame and sash showing the sash holder associated therewith Fig.3 is a fragmentary end elevation of the sash and showing the sashfastener in end elevation; and

Fig. 4 is a longitudinal vertical sectional view of the sash fastenerremoved.

llcferring in detail to the drawings, the numeral 5 designates thevertically movable sash while Gdesignates one of the side rails of thesame, the inner face of the side rail of the sash 5 being provided witha rectangular recess 7. A cylindrical recess 8 is also provided in thisrail 6 rearwardly of the recess 7. The opposed vertical faces of theside walls of the recess 7 are provided with parallel longitudinalgrooves 10.

Adapted for longitudinal movement in the recess 7 and insertihlyaccommodated therein is a substantially rectangular housing or plunger11 which is open at one side to receive a roller 12 mounted upon a shaft7 13 in the side walls of the casing 11, the ends of the shaft beingslidably engaged in the longitudinal grooves 10. The rear end of thehousing 11 is formed with a thickened part, the inner surface of whichis curved longitudinally, as indicated at 13. One or more rollers lt arepositioned on this inner curved surface and are adapted to bind againstthe roller 12 and the rear end of this curved wall should the rollerstart to rotate in a counter-clockwise direction. The rear face of thecasing 11 is formed with a rearwardly extending projection 14. A disk 15having a central aperture is mounted upon a screw 15, whichis secured inand extends rearwardly of the projection 14:. .This screw is equipped atits free end with an enlarged end 17 which at times abuts with the.bottom of the recess in the sash rail and prevents undue inward movementof the housing 11. A coil spring 16 encircles the projection 14 andbears against the disk and normally urges the same toward the head 17.The disk 15 normally bears against the bottom of the circular recess inthe rail 5.

posite end of the coil spring.

The embodiment of he invention herein I shown and described isconsidered the pre- 7 'ferredforim but it is to be understood that thesame is susceptible to variousmodifications, and that my'limits of suchmodlfication are governed onlyby what is claimed.

What is claimed is':-+

In a sash fastener a vertically movable sash having a recess 1n one sidethereof, a

housing s-lidable in the recess, the rear wall and the bottom wall ofthe housing being formed with a thickened part, the surface of whichbeing longitudinally curved, aroller journaled in the housing andmovable over one rail of the window frame, rollersmovable over thecurved surface and adapted to vbind against the first-mentioned rollerto lock the same against rotation upon the lowering of the sash,randexpansible means urging the housing toward the sash frame.

In testimony that I claim the, foregoing as my own, I have heretoaflixed my signature in the presence of two witnesses;
